SPECIFICATION forming part of Letters Patent No. 367.913, dated August 9, 1887.

Application tiled May 19, 1.887. Serial No. 238,789. (No model.)

To aZZ whom it may concern: Be it known that I,WILLIAM K. HOAGLAND, a citizen of the United States, residing at Peru, in the county of La Salle and State of Illinois, have invented a new and useful Improvement in Qultivators, of which the following is a.

specification.

My invention relates to straddle-row cultivators, and has the object to improve the construction, adaptation, and operation of parts connecting the spring with the drag-bars.

Referring to the drawings, like letters refer to like parts in all the figures, in which Figure lis a perspective view of that part of a straddle-rowcultivator in which my improvements are embodied. Fig. 2 is a perspective view of the clevis as improved by me; and Fig. 3 is a perspective view ofthe bail, showing its construction.

A is the arched axle provided with the wheel arm a, sand-capb, and thlmble c B are the drag-bars attached-to the yoke cl. C is the clevis attached tothe said thimble, and the said yoke pivotally connected tothe arms of the clevis; and D is the spring attached to the axle, all of ordinary construction, except as modified to be adapted and used with my iluprovements, as hereinafter shown.

H is a bail, having the closed end h and the arms m and n provided with perforated ends and loosely pivoted upon the axle A. The said arm m is crooked, elbow-like, having means for connecting the spring, asV shown, under the axle.- the bail below the axle, that the main force of the spring will be spent against the axle when the plows are at work and have an increasing force upon the plows as they are elevated, as will be understood by inspecting the drawings.

p is a bar, rearwardly projecting from the lower arm of the clevis, and providedwith the downwardly -projecting leg q, bearing upon the closed end of the bail, and Z is a link having one end pivotally connected to the elbow of the arm m and the other end connecting to the spring, as shown in the drawings.

In operation, the drag-bars are pivotal] y The spring is connectedto' connected to the horizontal part of the axle by 'the clevis and thimble, the bail loosely pivoted -without a liability of loosening the set or any 6o change of the bail or spring-connection, all of which will be understood by inspecting the drawings.

Having thus described my invention, I claim' 1. y In a straddle-row coltivator, the bail having the closed end and pivotal upon the axle, in combination with the clevis provided with the rearwardly-projecting bar and downwardly-projecting leg, substantially as and for the 7o purpose shown.

2. In a cultivator, the bai-l provided with the elbowed or bent arm m, and pivotal on the axle, said arm extending first downwardly from the axle and thence rearwardly to the closed 75 end ofthe bail, as shown, in combination with the spring connected to said arm below the axle, substantially as and for the purpose set forth.

3. In a cnltivator, the clevis and the leg q, SO projecting downwardly below the drag-bars, in combination with the bail pivotal upon the axle, and a spring to hold said bail bearing against said leg, substantially as and for the purpose set forth.

4. In a straddle-row cultivator, the combination of the axle A, drag-bars B, yoke d, clevis C, bail H, and spring D, all constructed, arranged, and operating substantially as and for the purpose set forth.
